This is a series of posts that cover the features of Hitachi’s new enterprise storage platform, the VSP (Virtual Storage Platform), also sold by HP as the P9500 array. Previous posts:
Hitachi Virtual Storage Platform: Disk Drive Architecture
Hitachi have modified the VSP array to provide significant performance improvements over the previous USP [...]
The recent proposed acquisition of 3Par by Dell and/or HP has made me think a little more about the direction the storage industry is taking in terms of their storage array design architecture. Since storage arrays became a category of devices in their own right, we’ve seen the growth of the monolithic, sometimes [...]
Here I am again on the start of another vendor blogging day. As the title of this post suggests, this will be a trip to see Hitachi, or HDS (Hitachi Data Systems) if you prefer. The Bloggers Day is taking place over two days and is located in San Jose, just south of San Francisco [...]
A little discussion on Twitter between myself, @BasRaayman, @UltraSub and @esignoretti got me thinking about the evolution of VPLEX and the whole caching thing. It’s something I mentioned on one of my previous VPLEX posts and it could have significant impact on designing and implementing VPLEX solutions. Here’s the [...]
It’s been reported in a few places that yesterday Barclays (UK bank) suffered an issue with a “disc array” (presumably they mean disk array) that took out their ATM and online banking systems. See the comments here and here.
Allegedly, Barclays now use USP-V arrays as their [...]
So HDS’s announcement has turned out to be a complete disappointment. What it’s not:
It’s not new hardware. It’s not providing more physical capacity. It’s not providing dynamic tiering. It’s not providing enhanced replication technology.
What is on offer is the ability to cluster USPs – a feature called Hitachi High Availability Manager. [...]
Well, I truly hope not. Let me just explain what I’m talking about and things may become a bit clearer.
HDS have started their viral marketing for an announcement being made on 27th May. Claus Mikkelsen’s latest blog entry asks us to guess what the announcement will be, based on an acronym of [...]
So the rumours (here and here) are true. Here’s the announcement to prove it. HDS are going to support 750GB SATA II drives in the USP.
This is an interesting position HDS are taking as thin provisioning will be able to take use of the enhanced drive capacity [...]
According to Wikipedia, lightning can travel at a speed of 100,000 MPH, however I think storage vendors are even faster than lightning when it comes to highlighting or dissing the competition.
Mere microseconds after reading Claus Mikkelsen’s blog on the USP-V SPC figures, there are posts from [...]
After the recent EMC announcements on DMX-4, I promised I would look at the question of whether the new DMX-4 is really as green as it claims to be. I did some research and the results are quite interesting.
Firstly we need to set the boundaries. One of the hardest part of comparing [...]
